Money, stocks, and FOSS

I am very new to the Stock & Wall Street world but after a year in it I’ve gotten to the point where I can no longer afford (financially) to NOT have a web based trading platform like Robinhood, but just like all other things that are good for the layman in this digital age: google has to own it, and so from what i’ve seen so far, almost all other of these trading platform are on google play services/store.

My questions:

  1. Does anyone know if F-Droid has something “like” it/them?

  2. If so, does it have security problems, or trading problems like what Robinhood had back in 2021?

  3. If F-Droid doesn’t, does anyone know if some masked & caped crusader in the F-Droid Dev world has plans to make one?

  4. If no to the previous 3, does anyone know of any other FOSS App store (Aurora is the only other one that comes to mind) that does?

  5. If no to the previous 4, is the only solution to purchase a completely new and separate phone (burner/walmart phone?) for just the sole purpose of being able to trade?

I think i found something, but it’s not an app (for any one who’s curious):
